The Sixth International Ground Validation Workshop will be held November 5 -7 in Rome, Italy, at the headquarters of the National Research Council of Italy ( CNR ), Institute of Atmospheric Sciences and Climate ( ISAC ). The workshop is organized in coordination with NASA’s Precipitation Measurement Missions Science Program. The meeting will focus on activities related to the upcoming launch of the Global Precipitation Measurement mission's Core Observatory, including: Developing consensus plans for post-launch assessments of satellite algorithms/products using GV measurements Reviewing

Typhoon Francisco was headed toward the islands of southern Japan when the TRMM satellite had a good view on October 22, 2013 at 0933 UTC. Francisco was weakening and had estimated winds of less than 75kts (~86 mph) with this TRMM pass. An analysis derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown overlaid on an enhanced infrared image from TRMM's Visible and InfraRed Scanner (VIRS). This analysis showed that the most intense rain was falling at a rate of over 75mm/hr (~3 inches) in a location well to the southwest of Francisco's center of circulation

A month ago hurricane Manuel caused caused landslides and extensive flooding along Mexico's Pacific Ocean coast. Recently formed hurricane Raymond is expected to cause heavy rainfall in nearly the same area. The TRMM satellite flew directly above hurricane Raymond on October 21, 2013 at 0111 UTC (October 20 at 6:11 PM PDT). TRMM Precipitation Radar (PR) data from that orbit shows that hurricane Raymond contained towering thunderstorms on the western side of the eye wall that were reaching to heights above 15km (~9.3 miles). TRMM PR also recorded precipitation in Raymonds eye wall that was

Super typhoon Francisco is headed toward Japan as the country is still recovering from typhoon Wipha. The TRMM satellite flew above the western Pacific and caught a good view of super typhoon Francisco on October 20, 2013 at 0947 UTC. A precipitation analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments found that rain was falling at the extreme rate of over 207 mm/hr (~8.1 inches) in an area of violent storms southwest of Francisco's eye. TRMM's Precipitation Radar (PR) discovered radar reflectivity values of over 53dBZ in heavy precipitation south of Francisco

The sixth super typhoon of 2013 called Francisco developed in the Western Pacific Ocean on October 16, 2013. The image on the left was made from data collected as the TRMM satellite passed over on October 18, 2013 at 1002 UTC when super typhoon Francisco was located west-northwest of Guam. A rainfall analysis that used data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown on the left overlaid on an enhanced infrared image from TRMM's Visible and InfraRed Scanner (VIRS). TRMM PR found that rain was falling at a rate of over 113 mm/hr (~4.5 inches) in powerful

At 1500 UTC (11:00 AM EDT) the National Hurricane Center (NHC) upgraded TD11 to tropical storm Jerry. Tropical Depression ELEVEN (TD11) developed in the central Atlantic Ocean on Saturday September 28, 2013. Southwesterly wind shear reduced TD11's strengthening until this morning. TD11 was having strong bursts of convection when the TRMM satellite flew over earlier at 0929 UTC (~ 6:29 AM Local Time). The image on the left shows a rainfall analysis that uses TRMM Precipitation Radar (PR) data from that orbit. It shows that rain was falling at a rate of over 150 mm/hr from some powerful

Western India has been having intense monsoon rainfall since September 21, 2013. This has resulted in widespread flooding in the west Indian state of Gujarat and reports of at least three related deaths. India had record breaking flooding in the northern state of Uttarakhand in June 2013 with more than 6,000 people killed. Near real-time TRMM Merged HQ/Infrared Precipitation (3B42) data were used in the rainfall analysis above. Rainfall total estimates from these space satellite data for the seven day period from September 20-27, 2013 were used. The highest totals of almost 800mm (~31.5 inches

The most powerful typhoon of 2013 hit southern China with reported winds of 95.6 kts (~110 mph) killing at least 20 people. The TRMM satellite had a fairly good view on September 22, 2013 at 0923 UTC as typhoon USAGI's eye was very near the coast of southern China. TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments showed that in addition to the extreme winds reported there were areas just south of USAGI's eye where rain was falling at a rate of over 169mm/hr (~6.7 inches). TRMM sliced through USAGI and found that heights of storms within USAGI were reaching only about 12km

Mexico's Pacific and Gulf coasts were both inundated by deadly tropical rainfall at the same time. Hurricane Manuel dropped extremely heavy rainfall along Mexico's Pacific coast. At least 55 people have been reported killed in Mexico due to flooding and landslides caused by extreme rainfall. Hurricane Ingrid weakened to a tropical storm and came ashore from the Gulf Of Mexico into the state of Tamaulipas near La Pesca, Mexico on Monday September 16,2013. The approximate 0000Z and 1200Z locations of the tropical cyclones are shown overlaid in white. The TRMM-based, near-real time Multi-

The TRMM satellite again flew directly above category two typhoon USAGI, with maximum wind speeds of about 120kts (~130mph), on September 21, 2013 at 0209 UTC as USAGI was passing between Taiwan and the Philippines. Rainfall data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments are shown in this image. TRMM PR found rain falling at a rate of over 134 mm/hr (~5.2 inches) in USAGI's eye wall where radar reflectivity values of over 51dBZ were returned to the satellite. A weaker Typhoon USAGI is predicted to hit Hong Kong tomorrow with wind speeds of 80kts (~92 mph).
